Frequently Asked Questions
- Is my password safe when testing login flows?
- Test credentials are encrypted in transit and never stored after the check completes. We recommend using a dedicated test account with read-only permissions.
- What login types does the validator support?
- The validator supports standard username/password forms, email magic links (with webhook verification), OAuth redirects (Google, GitHub), and custom SSO flows.
- Why should I test login from multiple regions?
- CDN configurations, geo-blocking rules, and regional DNS issues can cause login to fail in specific countries while working perfectly locally. Testing from India, UK, and USA catches these regional failures.
